To all whom t may concern.'x

Be it known that I, JAnEz D. 'HAR'NnsBEuat Atlanta, in the county'of Fulton and State of Georgia, have'invented certain new vand useful Improvements in File-Cabinets;

yand I do hereby declare the following to be a full, clear, and exactdescription ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same..v y

This invention relates to furniture, andy more -especially to file cabinets; and the object 0f the same is toproduce a cabinet of this character in which books, records, ac-

counts, and otliei articles can be tiled in such manner that they may be inspected at any I may saythat 'it has been my intention to divide a large city directory into signatures or booklets whereof each contains the 'namesunder one letter of thealphabet, and

provide this device. with acoin-controlled mechanism so that when a`customer dropped Ain a penny he could actuate the setting mechanism to bring the desired booklet into position where `he could draw it forth for -an inspection, but as this is only one of many uses to which the invention could be put, I do not wish to be limited in this respect. Also' while I have herein shown and described the cabinet as containing a coin i mechanism, it is quite obvious that if the device is used only forfiling papers andl similar purposes where an outsider does not approach it, the coin mechanism Acan be omitted.

Broadly speaking, the invention consists 'in'a franrework having` upright guides, a ,pair 'of racks movable therein andv counterbalancing each-other (or in some cases av single movable rack .counterbalancedby a weight). setting mechanism for adjusting the racks (or rack) so that the desired drawer comes opposite an opening, and displacing mechanism for withdrawing or pro# jecting that drawer. I/Vhen the coin controlled mechanism is used, means ofcoursewill, be employed to lock the machine so'that 'its racks vcan not be set or its displacing mechanism moved luntil the coin isl inserted,

but whether the coin mechanism is used or not I find it advantageous to employ part of the locking mechanism for holding the'racks steady while the displacing device is being used.. cnn, a citizen of the VUnited States, residing Filing cabinets 'as generallyv constructed Ii'i some instances these the desired compartment is presented to the user. 'In the first instance the operator must move his hand, and if the cabinet tall may have' to use a step-ladder, to gain access to the proper tray.- In the latter in-I stance the revolving cabinet fills its case'and -is turned to bring'- the desired trayto the user. In the present invention the casing is twice the size of the racks containing the drawers or trays, .andmeans are' provided for `moving the racks up and down. I find there is always plenty of room at tlietop of a store, ofiice or apartment, and therefore there is no objection if-this cabinet be made quite tallas may be required if its drawers or trays are individually deep. On the as sumption, however, that they are rather shallow, it is quite possible to build this device so that it stands no higher than the average man, and mount it onv a pedestal or stand or desk, so-that all` its parts -are in rrED srA'rEs rATnN-T OFCE.:

tion of parts, their materials, and their exact details of Aconstruction are not essential to the present invention. My preferred manner of carrying out the same is. described and `claimed below and illustrated in the accompanyingdrawings wherein- Figure l'is a left lside elevationof this cabinet 'with its casing removed, and Fig. 2

is a fron't elevation. Fig. 3 isan enlarged vertical section on the line 3 3 of Fig. 1, Y

and Fig. 4L is a horizontal section on the line 4-4 of Fig. 3. Fi'g. 5 is av perspective detail of theldisplacing frame, Fig.' 6 a perspe'ctive detail of a part of the locking mechanisin, and Fig. 7 a perspective detail of the cushion. `F ig. 8 is a perspective detail of one of the racks, showing one tray in place.

and the space from which another has been y removed. Fig. 9 is a. perspective detail of a plurality of shelves. Figs. lO and 11. 4are vertical sections at right angles to 'each other Vslightly,modified form of tray containing a j i through a modified or simplified type of the invention as will be explained below. Fig. 12 is an enlarged perspective detail of the coin controlling mechanism, Fig. 13 a sectional detail through theA wedge-shaped block and the shelf on which it slides, and Fig. 14 across sectional detailv of the coin chute.

In Fig. 1 of the drawings is seena pedestal 1 by which the framework and housing`2 of this improvedcabinet is supported above the floor, and when this pedestal is employed it contains a treadle 3 mounted on'a rock lever 4 whose inner end carries an upright rod 5 whereby the locking` mechanism is aotuated by the weight of an operator standing on the treadle. It will be clear without further illustration that the rod 5 might be raised by a hand lever or other means within the body or housing 2 ofthe cabinet and projecting therefrom so that it could be ma! nipulated by the operator, but the type of the invention shown in Figs. 1 and 2 is-intended for use in public places and will be described accordingly. The framework contains upright and preferably L-shaped guides 64 in which move two racks designated as a whole 'bythe numerals 7 and S in Figs. 1, 3

and 4, and these racks counterbalance each be obvious without further illustration that the 'drawer or tray might be displaced by pushing it from the operator so as to project it from the other side of the casing, and I Wish togive this breadth to the word displacing throughout the present specification. The drawers are shown in the accompanying drawings as rather ilat trays, each intended to hold a single article like a pamphlet or booklet, but in Fig. 9 I have shown the tray as composed of a frame .19 having a plurality of cleats 15 withinlits side bars on which slide a plurality of smaller trays or shelves 16 each perhaps quarter the depth of the frame 19. The lowermost shelf carries'a finger 17 at its front end rising so as to overlap the second shelf, and the second shelf carries another finger 18 rising sufficiently to overlap the third shelf. and three shelves are suicient for the illustration. When this frame 19 is displaced it brings the various shelves with it out into view7 and if what is desired by the operator is not found on the uppermost shelf, it can be moved on its cleats15 to expose the next shelf, and this action canv be repeated to ex- -posethe lowermcst shelf. This View is given to show that the construction of each tray may itself be such that the mattercontained therein may be subdivided. In other words,

if each drawer contains one letter of accounts or the like, each shelf in that tray could con- -tain one name under that letter and therefore the entirecontents can be divided on the letters of the alphabet and then subdivided as much as its capacity will allow.

The displacing mechanism illustrated herewith consists of a frame 2O best seen -in Fig. 5, the salne having two pairs of side bars 21 and-22 and a common frontbar 24 of a size to close the opening. 14, this fro-nt bar carrying a handle 23 by which the frame may be manipulated. The side bars travel in .guides 25 in the main frame, and flexible cables or chains 26 lead from them over pulleys 27 to weighted pistons 28 fitting rather parts, but it is obvious that any weight or,

spring might be employed to house the frame after the device has been used. Each.

side bar of the frame carries a lug 30 at its rear end projecting inward beyond its guide 25, each drawer or'tray 13 carries a corresponding lug 31` at its rear end Vprojecting outward beyond'its cleat 12 and adapted to be engaged by the lug 30 when the frame is drawn outward.

An important point in the successful operation of this machine (best illustrated in Fig. isthat the cables or chains 9 and in fact the entire suspending or counterbalancing mechanism must be so adjusted and constructed that whena tray in one rack comes directly opposite the displacing mechanism and stands within one side of the frame 20, the cleats 12 in the other -rack stand within the opposite side. Then when the frame is withdrawn two of its lugs 30 engage those on one tray and withdraw it, while its other lugs 30 p ass alongside the cleats 12 of the opposite rack and do not withdraw a tray therefrom. It follows that means should be provided for checking the vertical adjustment of theracks at times when a tray in one or the other rack is exy actly opposite the opening 14. The lugs on the frame 20 can never engage those on Figs. 1,3 and 6.

'is that shown herein which consists of eX- tending the shaft 34 of the drum'll for- Ward, through a front drum 35 if one be employed, and through the frontI of the housing 2; and providing it with 'a crank 36 having a handle 37. The tip of the cranlrv constitutes an index 38 which may move v over va dial 39 carrying letters as seen-in Fig. 2, and if the contents of the various trays contain matter which -is indexecl.,un

whether the locking mechanism'described below' 1s employed or not, and if the invention is used as a le cabinet where it is accessible only to the operator, it may vnot be necessary -to employ the locking mechanism because the operator can not withdraw .artray unless itl is directlyoppositethe opening. It is necessary in all cases, however, 'thatl the 4travsfin onerack bear matter lettered A, C, E, et cetei'a, while the trays in the other bearmatter lettered B, D, yF, et cetera.

The locking mechanism is best seen in is fixed a toothed wheel'40, and slidably mounted in guides'41 in the main framework is an upriglitrod 42 having its uppeil end formed into-the shape of a .bolt 43 adapted to engage between the-teeth on the wheel 40 when any tray 13 is directly opposite the opening 14. The rod 42 also carries a linger or a pair vof fingers v44projecting downward, and standing above notches 45 'in the inner side bars of tlie frames. As shown this lrod falls by gravity and the tips ofthe fingersnoriiially engage the notches and hold the fraineindocked position, while the tip of the bolt 43 is.dis

engaged from the wheel 40 on the drum.

shaft and therefore the setting mechanism is unlocked. AAs above stated, this lock may be actuated` by any suitable means such as.

a hand lever or plunger, although when the cabinet is for public use l prefer to lemploy a plunger whose action is controlled by a coin mechanism as set forth below. The

' hand lever or plunger therefore constitutes the manual controlling means for lifting the rod v42. lVhen it is lifted it rst ieleases or unlocks the frame and then locks thel racks against vertical movement. I

The operation of so much of the machine as has been described is as follows: Manipulating the crank 36 by its handle 3T until the index 38 stands opposite the letter desired, turns the drum shaft and actuates the setting mechanism to raise one rack and lower the other and bring the corresponding tray opposite the opening 14.V The lock-I actuating mechanism is thenlmanipulated and the rod 42 rises, its'bolt 43 locks the This occurs- O n the drum -shaft 34 v I JtliisLraClgpver.,drums l0', and `counterbalancing weights 8 are connected by othern' wheel 40 against-rotation, and -thercforeft'he setting mechanism can no: longer be moved. Its fingers 44 disengage the notches .455, and

.then `the operator grasps the handle 23 andi The proper pair p70 draws out. the frame-.20. of lugs 30,0n the latterengagefgthe lugs 31.011 the tray desired, andthe` la'tterAis drawn out through vthe. opening 14 into view. yIf the contents of this tray be {sub-v divided by'means ofshelves l6as-Seen. -in 7 Fig..9, they are. manipulated asalready described.. lVhether'the contents are to be removed, inspected, or added to, as -thus far described .the operator must hold on to theyv handle 23 because its release would permit the descent of the weight 28- which would restore the frame 20 to its closed position and carry the vtray back into. its rack. Any

rsaiitable means may be provided, however,'

for holding the Vdisplacing 'frame 2O in its g distended position, and l will describe Vone such means below.

In the' simplerform of machine ,shownA lin Figs. y10 and 11,'the same frameworlgfhousing, setting mechanism, and traystinay ybe employed but I prefer to usef-bivitfaasingle rack Tf of double height and mount all the tiays therein, Cables or chains 9; run ,from

cables or chains 9. with other drums 10 on the single` shaft 34. .The weightv is shown ,in Fig. 10 in section,` asbeingfin pieces which may be added 'asthe vrackf andv its trays lbecome heavier.. TheI frame 20'of the displacing:mechanism is here madesin? gle, and its lugs engage those onthe trays wheneverone of the latter comesopposite the opening 14 as shown in Fig. 11. This simpler type may be provided'with the vlocking mechanism above described, Vif `it is desired to prevent movement of the rack when -the displacing mechanisml is ybeing actuated, but Ido not consider it necessary bef 'drawn and uponwhichv they rest when in y 'these parts to their housed position is ein- V use. But if the mechanism for restoring ployed, some such device as the plunger 46 indicated in Fig. 11 will be needed to trip said mechanism and release the frame.: In' Fig. 1 the numeral 46 designatesjabutton ing lever 47 and the lower end of the lever is connectetd with a yplunger '48 which carries l a wedge-shaped lock 49 that stands beneath a shoe 50 at the lower end of the rod 42, and 130 i proJecting through the casing from a swing- .nisrrily another lock (or, more properly, a

therefore when the plunger is driven to the rear the wedge raises said shoe on the rod `with the result described above. The action of the plunger rod on the block 49 may be controlled -by a coin mechanism, illustrated in detail on the last sheet of drawings, but it is obvious that no such coin mechanism is needed for the simpler type of the invention shown in Figs. 10 and 11.

The coin mechanism includes a coin chute 51 which may have the usual safety devices such as a magnet 52 for arresting a slug of magnetic material rather than copper, 'an

opening 53 for dropping out under-sized coins, and a shelf 54 at the lower end of the chute and having a narrow opening 55 for dropping disks which are thinner than the propercoin. A wedge-shaped block 49 is slidably mounted on said shelf beneath theshoe ofthe locking mechanism, and a 'plunger 48 is connected with its operating knob or button 46 by any suitable mecha.- nism suchas the lever 47 described above.

The plunger 48 is held in a normally retracted position by any suitable means such as arsprin'g 56, and when projected it passes across the path of the coin at the point 57 and enters a socket 58 in the block xg49. Obviously if nocoin is present the' block is not moved, but if the proper coin-rests at 59 on the shelf 54, movement ofthe plungerwill move the block along said shelf, and the Wedging shape of the block will cause the rise of the shoe 50. As best seen in Fig. 1, the lever 47 carries the knob or button 46 above the shelf over which thefram'e 20 isdrawn out, and the coin chute 51 is carried up throughv the frame 20 as seen in Figs. 3

and 4,. and its mouthis justunder the dial 39 afs seen in Fig. 2. y'With this coin mechalatchQ is by preference employed, and this l'atch'vis automatically operated by the trea- 'dle 3 when the operator steps thereon to place his coin in the chute. The rod 5 de- 'scribed above is forked as shown at 60,v and its rear arm 61 passes up through a hole in the' shelf 54 and has its tip beveled at 62 and underlying the block 49. The latter is provided with a notch 63 with which said tip may engage when the block is pushed to the rear. The front arm 6 4 of the fork passes up' within the main framework and is itself forked ,or provided with fingers 65,

lthese fingers underlying the inner side bars 21 and 22 of the frame 20. Near their rear ,ends said side b'ars are Vnotched in their within reachof the setting mechanism, and following instructions he turns the crank 36 until the index 38 points to the letter desired. Now he inserts the coin which, if a vproper one, falls to the point 57 and rests setting mechanism. 'The operator now withdrawsvthe frame and the'tray he has selected, and when the notches 66 of the frame come over -the Iingers 65 the latter latch the frame in its withdrawn position and hold it there until he steps off the platform. Y ,Hav-- ing inspected the booklet or done whatever else is permitted by the withdrawal of a tray, if he` should step ofi' the platform without restoring the frame to its proper position, the fork falls, its tip 62 releases the block whichis immediately restored to the position shown in Fig. 13 by springs 69, the descent of the fingers releases the frame which is restored with its tray by the weights 28, and the withdrawal of the block from beneath the shoe 50 permits the descent of the rod 42 so that its fingers 44 lock the frame and its bolt 43 unlocks the setting mechanism for the two racks.

It will be obviouswithout further illustration-,and description that the coin-controlled mechanism and the A-lock and latch. would operate with equal success in the simplified form ofcabinet shown in Figs.

10 and 11, but as above stated I would not ordinarily use this mechanism in connection therewith. Also it will be obvious that it is notl necessary always to employ all of the details of the coir'i mechanism. For instance, some or allg'y of the safety devices might lbe used or ndt, or might be replaced by others if preferred. I have said that the coin runs down the chute to the point 57, but

if the magnet 52 be employed I prefer that one leg shall be longer than the other so as to rest normally upon the bottom of the chute as shown at 72,5while the shorter leg stands off the bottom of the chute( so that a coin may enter at the point 73. The magnet is held in this position by a yoke 74 which passes around the chute and is connected at 75 with the plunger. Then now the coin is dropped in.place it comes to rest on the long leg at 72 and stands at the point 73 opposite the shortleg, so that if instead of a' copper coin it should be a slug of magnetic material, it is attracted by and held against the magnet.' The first initial movement of the plunger carries the yoke 74 to the rear and inoves the magnet off the chutev at the point 72, and if itbe a penny that has been dropped into vplace the same is then released and falls to the point 57 in Fig. 13. There it rests at 59 onthe shelf 54, and further movement of' the plunger clamps tliis penny between the end of the plunger and the front fa'ce of the block 49.

The widest -latitude mustbe allowed the vowner as to the use of this-device. As sug- 'gested above, the trays may contain inforf mation indexed under the letters of the alphabet, so that any tray andfits data be-` trays from. time to time. Q Again, the device may beus'ed- 'strictly as" an account or filing cabinet, in which case the` operator gains access to a tray and -puts something into it;

but that case thelcoin mechanism would obviously be omitted. These and other uses of the device may necessitate alterations in its general structure, `and will doubtlessre- 4 quire adaptation of the trays tothepurpose forgwhieh they are to be used, and one instance of such adaptation is shown in Fig. 9.
